(D)Questions 35 and 36. The graph shows the velocity of an object during the interval 0 ≤ t ≤ 9.
The object attains its greatest speed at t =
3 sec
5 sec
6 sec
8 sec
The object was at the origin at t = 3. It returned to the origin
during 6 < t < 7
at t = 7
during 7 < t < 8
at t = 8An object in motion in the plane has acceleration vector a(t) = sin t, e−t
for 0 t 5. It is at rest when t = 0. What is the maximum speed it
attains?
